M94 The Croc’s Eye Galaxy (CVn) - A short glimpse at the crocodile, before running away

Messier 94 (also known as NGC 4736) is a spiral galaxy in the mid-northernconstellationCanes Venatici. Although some references describe M94 as a barred spiral galaxy, the "bar" structure appears to be more oval-shaped. The galaxy has two ring structures.
M94 has an inner ring with a diameter of 70 arcseconds (″) (given its distance, about 5,400 light-years) and an outer ring with a diameter of 600″ (about 45,000 light-years). These rings appear to form at resonance points in the disk of the galaxy. The inner ring is the site of strong star formation activity and is sometimes referred to as a starburst ring. This star formation is fueled by gas driven dynamically into the ring by the inner oval-shaped bar-like structure.
M94 seems to be known as either the Croc’s Eye Galaxy, or the Cat’s Eye Galaxy ... 

Months of cloudy nights, and only at the moment where spring/summer night are getting too short, there’s finally a fluke clear night. In the run-up to the night, all the weather-apps all said ‘yes’, but the clouds said ‘no’. Only at the moment where the weather-apps finally recognised their defeat, and admitted it was going to be ‘no’, the sky suddenly cleared.

I brought out the scopes (C8 EHD, C11 EHD), and while the C8 was running it’s program, I continued to get the C11 into BAU-mode. A new test-target: M94, only 2 hours integration time, astronomical darkness is eroding away fast, lots of satellites, but I tried to optimise all of that in the processing.

A bit of a crude image, grainy, too short on time … I rather see this as a dragon-like crocodile's eye, instead of a cat's eye ...  but it feels like finally having water (clear sky) in a desert of cloudy nights.
